Sponsored by Assuta Medical Center · Observational
This study examines permanent disability related to diabetes using routinely collected data from the National Insurance Institute of Israel.
The study will evaluate how often diabetes is recorded among people who have been granted permanent disability and whether the frequency and severity of diabetes-related disability differ by geographic area and over time. It will also examine the distribution of disability according to the statutory level of diabetes-related impairment.
Data from 2020 through 2025 will be analyzed. The study is observational and retrospective, meaning that it uses information that has already been collected for administrative purposes. No participants will receive an intervention, medication, or additional medical examination as part of the study.
The main goals are to describe national and regional patterns of diabetes-related permanent disability, identify changes over time, and determine whether meaningful geographic differences exist. The findings may help improve understanding of the burden of diabetes-related disability and support future health care, prevention, rehabilitation, and social-policy planning.
This retrospective observational study will evaluate the burden and distribution of diabetes-related permanent disability using administrative records from the National Insurance Institute of Israel for the years 2020-2025.
The analysis will include individuals with recognized permanent disability and will identify records in which diabetes is included among the conditions contributing to the disability determination. Diabetes-related disability will be characterized according to the statutory impairment categories used by the National Insurance Institute. Geographic variation will be examined across the major administrative districts, together with changes in the number and proportion of diabetes-related disability records over time.
The study will assess temporal and regional patterns in diabetes-related permanent disability and explore whether the distribution of disability severity differs between geographic areas or study years. Where appropriate, rates, proportions, comparative measures, and statistical tests of geographic and temporal heterogeneity will be used to describe these differences.
Because the study is based exclusively on previously collected administrative data, participants will not undergo additional examinations, interventions, or changes in medical care. The study is intended to provide population-level evidence regarding the social and disability burden associated with diabetes and to identify geographic or temporal differences that may be relevant to prevention strategies, health-service planning, rehabilitation, and disability policy.

Records containing sufficient information to determine whether diabetes mellitus contributed to the permanent disability assessment.
For diabetes-specific analyses, individuals with diabetes mellitus documented as a recognized condition contributing to permanent disability.
Exclusion Criteria:
-
All individuals with a recognized permanent disability recorded by the National Insurance Institute of Israel between 2020 and 2025 will constitute the study population. Within this population, records in which diabetes mellitus is documented as a condition contributing to the permanent disability determination will be identified and analyzed. Diabetes-related disability will be classified according to the applicable statutory impairment categories. Geographic and temporal patterns will be evaluated across administrative districts and study years. This is a retrospective observational study based on routinely collected administrative data; no intervention, treatment, or additional clinical assessment will be performed as part of the study.
Diabetes co-morbidities
Proportion of permanent-disability records in which diabetes mellitus is recognized as a condition contributing to the permanent disability determination, overall and by geographic district.
Time frame: 8 years
diabetes-related permanent disability severity
Distribution of diabetes-related permanent disability according to statutory diabetes impairment categories, compared across geographic districts and calendar years.
Time frame: 8 years
Plan to share: No — Individual participant data will not be shared because the study is based on administrative records provided by the National Insurance Institute of Israel under institutional, ethical, and data-protection restrictions. The investigators are not authorized to distribute individual-level data to third parties. Aggregated, non-identifiable study results may be reported in publications and scientific presentations.
